How to get @interface parameter in jersey WriterInterceptor Implementation

问题

I have an interface, for example

@NameBinding
@Retention(RetentionPolicy.RUNTIME)
public @interface AutoLogged {
    boolean query() default false;
}

How can I get query parameter in interceptor implementation?

@Provider
@AutoLogged
public class AutoLoggedInterceptor implements WriterInterceptor {
    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void aroundWriteTo(final WriterInterceptorContext context)
            throws IOException, WebApplicationException {
        try {
            final String methodName = this.resourceInfo.getResourceMethod().getName();
            BasicAutoLoggedProducer.makeCall(methodName);
        } catch (final Exception e) {
            e.printStackTrace(System.err);
        } finally {
            context.proceed();
        }
    }
}

I can not find it in context.getPropertyNames. I see annotation AutoLogged with getAnnotations method. How to retrieve parameter query from interface?

回答1:

You can simply do

AutoLogged annotation = resourceInfo.getResourceMethod().getAnnotation(AutoLogged.class);
if (annotation != null) {
    boolean query = annotation.query();
}

"and want to set parameter query"

Not exactly sure what you mean hear, but if you mean you want to set the value at runtime, I'm not really sure the purpose and not really sure how to do it. Hopefully you men "get" instead of "set" :-)
